The committee voted 14-3 to send the nomination of John Negroponte to the full Senate
Voting against the nomination were Democrats Paul Wellstone of Minnesota, Russ Feingold of Wisconsin and Barbara Boxer of California.
They did not question Negroponte's qualifications and said they would not try to block the nomination, particularly with the pressing need for the post to be filled after Tuesday's attacks against the United States.
The previous U.S. ambassador, Richard Holbrooke, stepped down in January.
